A bridge is a tooth replacement that is made of two or more crowns. It is a staple of restorative dentistry, and can bridge the gap that missing tooth leaves, and can even provide a remedy for partial tooth loss.
The easiest way to explain how a bridge works is to think of a normal, non-dental bridge. Bridges have to be reinforced on two points in order to be able to handle the pressure of being used, so the structure does not collapse. Dental bridges also need pillars of support. The adjacent teeth are usually used as pillars, and more and more frequently, dental implants as well, as they serve as artificial tooth roots and can anchor the bridge.
If you only have one missing tooth, the adjacent teeth are usually used as the pillars to the bridge. These two teeth will be prepared in the same way that teeth getting crowns are prepared, and then an imprint will be taken. The dental technicians will then make a three unit bridge, one with the missing tooth I the middle, and two smaller, cap like ends that go atop the teeth next to the missing one. Bridges are considered fixed dental prostheses, and are adhered with very vigorous adhesive.
Bridges just like the crowns that can be found on them, can also be made with a metallic base, or with a metal free zirconium oxide base. Zirconium based bridges enjoy an aesthetic advantage over their more traditional counterparts, but they are the same in terms of functionality and longevity. A good bridge, provided that the patient has good oral hygiene and visits their dentist regularly, can last up to 15 or even 20 years.
If you answered yes to one or more of these questions, then we can recommend the zirconium oxide based dental bridge for you. If most of these questions were answered with a resolute and firm “no”, then you are probably better off with a metallic bridge.
